Electronic Arts and BioWare have revealed Shadow Realms, an online action RPG with a focus on asymmetric team-based gameplay. The title centers around a conflict between heroes on Earth and a parallel world called Embra, whose Shadow Legions have begun to invade Earth. A team of four players will control the heroes as they square off against a single enemy, also player-controlled, called the Shadowlord, and the game will reportedly have an episodic narrative stringing the various missions together.

The official website has been set up here, and players can register for the closed alpha here.
